GGT10 Compatible Cylinder Head - OS4A404000 by O.S. Engine  [OS4A404000]

Durability and fit for GGT10 heads

This O.S. Engine OS4A404000 cylinder head is supplied as an RC replacement for the GGT10 series. It acts as the combustion chamber cover and is intended for repair work or part renewal on compatible GGT10 engines from O.S. Engine.

For service, follow the engine maker's removal procedure, examine sealing surfaces and the head gasket thoroughly, then reinstall the head using the recommended fastener order and torque figures from the manual. Take care not to overtighten and check clearance around the glow plug and cooling ports.

As a maintenance item, fitting a new head can recover reliable compression and sealing, which supports longer component life. It is suitable for rebuilds when you are inspecting piston, sleeve, and carburetor settings to keep the engine running consistently.
